Method Detail

getOptions

public java.util.Map<ChannelOption<?>,java.lang.Object> getOptions()

Description copied from interface: ChannelConfig

Return all set ChannelOption's.

Specified by:

getOptions in interface ChannelConfig

Overrides:

getOptions in class EpollChannelConfig

getOption

public <T> T getOption(ChannelOption<T> option)

Description copied from interface: ChannelConfig

Return the value of the given ChannelOption

Specified by:

getOption in interface ChannelConfig

Overrides:

getOption in class EpollChannelConfig

setOption

public <T> boolean setOption(ChannelOption<T> option,
                             T value)

Description copied from interface: ChannelConfig

Sets a configuration property with the specified name and value. To override this method properly, you must call the super class:

 public boolean setOption(ChannelOption<T> option, T value) {
     if (super.setOption(option, value)) {
         return true;
     }

     if (option.equals(additionalOption)) {
         ....
         return true;
     }

     return false;
 }
 

Specified by:

setOption in interface ChannelConfig

Overrides:

setOption in class EpollChannelConfig

Returns:

true if and only if the property has been set

setAllocator

public EpollDomainDatagramChannelConfig setAllocator(ByteBufAllocator allocator)

Description copied from interface: ChannelConfig

Set the ByteBufAllocator which is used for the channel to allocate buffers.

Specified by:

setAllocator in interface ChannelConfig

Specified by:

setAllocator in interface DomainDatagramChannelConfig

Overrides:

setAllocator in class EpollChannelConfig

setAutoClose

public EpollDomainDatagramChannelConfig setAutoClose(boolean autoClose)

Description copied from interface: ChannelConfig

Sets whether the Channel should be closed automatically and immediately on write failure. The default is true.

Specified by:

setAutoClose in interface ChannelConfig

Specified by:

setAutoClose in interface DomainDatagramChannelConfig

Overrides:

setAutoClose in class DefaultChannelConfig

setAutoRead

public EpollDomainDatagramChannelConfig setAutoRead(boolean autoRead)

Description copied from interface: ChannelConfig

Sets if ChannelHandlerContext.read() will be invoked automatically so that a user application doesn't need to call it at all. The default value is true.

Specified by:

setAutoRead in interface ChannelConfig

Specified by:

setAutoRead in interface DomainDatagramChannelConfig

Overrides:

setAutoRead in class EpollChannelConfig

setConnectTimeoutMillis

public EpollDomainDatagramChannelConfig setConnectTimeoutMillis(int connectTimeoutMillis)

Description copied from interface: ChannelConfig

Sets the connect timeout of the channel in milliseconds. If the Channel does not support connect operation, this property is not used at all, and therefore will be ignored.

Specified by:

setConnectTimeoutMillis in interface ChannelConfig

Specified by:

setConnectTimeoutMillis in interface DomainDatagramChannelConfig

Overrides:

setConnectTimeoutMillis in class EpollChannelConfig

Parameters:

connectTimeoutMillis - the connect timeout in milliseconds. 0 to disable.

setEpollMode

public EpollDomainDatagramChannelConfig setEpollMode(EpollMode mode)

Description copied from class: EpollChannelConfig

Set the EpollMode used. Default is EpollMode.EDGE_TRIGGERED. If you want to use DefaultChannelConfig.isAutoRead() false or DefaultChannelConfig.getMaxMessagesPerRead() and have an accurate behaviour you should use EpollMode.LEVEL_TRIGGERED. Be aware this config setting can only be adjusted before the channel was registered.

Overrides:

setEpollMode in class EpollChannelConfig

setMaxMessagesPerRead

@Deprecated
public EpollDomainDatagramChannelConfig setMaxMessagesPerRead(int maxMessagesPerRead)

Deprecated.

Description copied from class: DefaultChannelConfig

Specified by:

setMaxMessagesPerRead in interface ChannelConfig

Specified by:

setMaxMessagesPerRead in interface DomainDatagramChannelConfig

Overrides:

setMaxMessagesPerRead in class EpollChannelConfig

setMaxMessagesPerWrite

public EpollDomainDatagramChannelConfig setMaxMessagesPerWrite(int maxMessagesPerWrite)

Description copied from class: DefaultChannelConfig

Set the maximum number of message to write per eventloop run. Once this limit is reached we will continue to process other events before trying to write the remaining messages.

Overrides:

setMaxMessagesPerWrite in class DefaultChannelConfig

setMessageSizeEstimator

public EpollDomainDatagramChannelConfig setMessageSizeEstimator(MessageSizeEstimator estimator)

Description copied from interface: ChannelConfig

Set the MessageSizeEstimator which is used for the channel to detect the size of a message.

Specified by:

setMessageSizeEstimator in interface ChannelConfig

Specified by:

setMessageSizeEstimator in interface DomainDatagramChannelConfig

Overrides:

setMessageSizeEstimator in class EpollChannelConfig

setRecvByteBufAllocator

public EpollDomainDatagramChannelConfig setRecvByteBufAllocator(RecvByteBufAllocator allocator)

Description copied from interface: ChannelConfig

Set the RecvByteBufAllocator which is used for the channel to allocate receive buffers.

Specified by:

setRecvByteBufAllocator in interface ChannelConfig

Specified by:

setRecvByteBufAllocator in interface DomainDatagramChannelConfig

Overrides:

setRecvByteBufAllocator in class EpollChannelConfig

setSendBufferSize

public EpollDomainDatagramChannelConfig setSendBufferSize(int sendBufferSize)

Description copied from interface: DomainDatagramChannelConfig

Sets the StandardSocketOptions.SO_SNDBUF option.

Specified by:

setSendBufferSize in interface DomainDatagramChannelConfig

getSendBufferSize

public int getSendBufferSize()

Description copied from interface: DomainDatagramChannelConfig

Gets the StandardSocketOptions.SO_SNDBUF option.

Specified by:

getSendBufferSize in interface DomainDatagramChannelConfig

setWriteBufferWaterMark

public EpollDomainDatagramChannelConfig setWriteBufferWaterMark(WriteBufferWaterMark writeBufferWaterMark)

Description copied from interface: ChannelConfig

Set the WriteBufferWaterMark which is used for setting the high and low water mark of the write buffer.

Specified by:

setWriteBufferWaterMark in interface ChannelConfig

Specified by:

setWriteBufferWaterMark in interface DomainDatagramChannelConfig

Overrides:

setWriteBufferWaterMark in class EpollChannelConfig

setWriteSpinCount

public EpollDomainDatagramChannelConfig setWriteSpinCount(int writeSpinCount)

Description copied from interface: ChannelConfig

Sets the maximum loop count for a write operation until WritableByteChannel.write(ByteBuffer) returns a non-zero value. It is similar to what a spin lock is used for in concurrency programming. It improves memory utilization and write throughput depending on the platform that JVM runs on. The default value is 16.

Specified by:

setWriteSpinCount in interface ChannelConfig

Specified by:

setWriteSpinCount in interface DomainDatagramChannelConfig

Overrides:

setWriteSpinCount in class EpollChannelConfig
